Have you ever wondered, "How can I use basic calculus?" Some truly simple examples are given early in the first ten pages including the fine details that you may need.
In retirement, after eight years of teaching chemistry and physics in high school, six years of teaching mathematics in college and 16 years of teaching computer science in college, a veteran teacher uniquely presents sixty plus pages of text and illustrations on the origin and purpose of differential and integral calculus. This presentation is regarded by some as a model of simplicity serving as a refresher for former students and as an introductory course for beginners.
Multiplication is multiple addition and Division is multiple subtraction. When the value of 0/0 is questioned, remember what is being asked. The question being asked, 6/2, is how many times must we subtract 2 from 6 on the number line in order to reach zero. Of course, the answer is three and this is the only answer. We ask the same question of 0/0. Correct answers abound. We may do this any number of times. The correct answer depends upon the value of t.
